The number of groups which should be created if the number of occurences is greater than loocv.limit.
loocv.limit
The limit below which the subsamples are created for a leave-one-out-cross-validation instead of a k-fold-cross-validation.
Value
This function returns a grid which contains the subsamples.
Details
This routine creates subsamples of species occurences based on the number of
occurences of the chosen species and the number of groups which should be created.
If the number of occurences of the chosen species is below the loocv.limit,
the groups contain only one member and the fold value will be ignored. The subsamples
can be used for a k-fold or leave-one-out-cross-validation.
